The invention provides a train speed measurement device and method, the device comprises a vehicle-mounted calculation unit, an automatic protection unit, a plurality of shared speed measurement modules and a plurality of Hall sensors, the axle speed of each axle of a target train is determined through each module, and the first speed and the second speed of the target train are further determined based on the axle speed. According to the train speed measuring device and method provided by the embodiment of the invention, the pulse signals of the axles are collected through the Hall sensors arranged on the axles in the carriages. Pulse signals sent by the Hall sensors in the carriages are received through the shared speed measurement modules in the carriages, the axle speeds of the axles are determined, and the first speed and the second speed of the target train are further determined based on the axle speeds. Any system needing to use the shaft speed can obtain the shaft speed from a unified speed measurement source, other systems are not needed for transfer, the data source is consistent, and the accuracy of train speed measurement is improved.

    本发明提供一种列车测速装置及方法,其中装置包括车载计算单元、自动防护单元、多个共享测速模块以及多个霍尔传感器,通过各模块确定目标列车的各个车轴的车轴速度,并进一步基于车轴速度确定目标列车的第一速度以及第二速度。本发明实施例提供的列车测速装置及方法,通过设置在车厢中各车轴的霍尔传感器,采集各车轴的脉冲信号。并通过各车厢中的共享测速模块,接收车厢中多个霍尔传感器发送的脉冲信号,确定各个车轴的车轴速度,并进一步基于车轴速度确定目标列车的第一速度以及第二速度。使得任何有需要使用轴速度的系统均可以从统一的测速源获取,无需其他系统中转,使得数据来源一致,提升了列车测速的准确性。
